11.2 Levels of Multithread Support
Each class in the DB Interface Module provides a specific level of multithread support. Application programs must ensure that each class is used appropriately, based on the safety level it provides. For a definition of thread safety levels, see Section 2.4.4 in the Essential Tools Module User's Guide.
Table 10 lists all the classes of the DB Interface Module with their MT-safe level.
